Any one here use this for there stock radio. just wondering how they perform.
I am looking at this option for my car. Was thinking about the secret audio system, but I have be told to stay away from them.

FYI here's the link.

I've used them and found them a pleasure to deal with. I haven't had the unit on yet since I'm still working the install. When I first contacted them about what I had, he was able to identify and respond based on the photos I sent. His response was always quick and courteous. Any issues are also resolved quickly. His work is not cheap, but certainly is quality.

Also, research American Classic Restorations in Uxbridge, Ma. They redid my radio and mounted a remote in the ashtray for CD changer I mounted in trunk. Completely stock looking.
